Aim and Objective: To assess and compare the shear bond strength of brackets bonded with two different self-adhesive systems with and without contamination (Water, Saliva and Blood) and to evaluate the effect of Salivatact on the shear bond strength obtained with Beauty Ortho Bond.
Material and Method: 15 premolars each (a total of 180) were bonded with Transbond XT plus, Beauty Ortho Bond and Beauty Ortho Bond with salivatact under various conditions i.e. dry, water, saliva and blood contamination. The shear bond strength and the ARI values were obtained and evaluated statistically.
Results: Transbond plus had the maximum bond strength in dry condition and when contaminated with water or saliva. The bond strength of Beauty Ortho Bond with and without salivatect was similar in dry condition and when contaminated with water or saliva.
The shear bond strength was lowest after the blood contamination in all the groups and highest for dry condition. Contamination with water and saliva resulted in similar strengths for all the groups. The bond strength achieved with all the three contaminants (water, saliva, blood) was similar when Salivatact was used.
Conclusion: Contamination decreases the bond strength for all the groups and this decrease is maximum in case of blood contamination. Bond strength of Transbond color change adhesive is higher than that of Beauty Ortho Bond under all conditions except when contaminated with blood using Salivatect. Beauty Ortho Bond using Salivatact had higher bond strength when contaminated with blood.
